GSM 4G 3G 2G Booster Cellular mobile signal

The GSM Booster comes with a large external antenna included in the package. This antenna has a gain of 10-12 dBi compared to the small internal antenna of a cell phone, which has a gain of 0-3 dBi. So, in a hard-to-reach place, you will have about four times the signal strength. This amplified signal will be transmitted from the outdoor antenna (point A) to another point where there is no signal at all (point B), eg house, basement, garage, back garden etc.

It can cover an area of 200-600 square meters in open space at point B, although this range may be lower if there are obstacles such as walls etc.

Amplifiers can only amplify an existing signal they will receive from point A where the external antenna is placed. Therefore, somewhere near your mobile phone should have at least a little signal available, (rooftop, balcony)
At point A, the received signal must be in one of the additional frequency bands: 800-960 MHz, 1710-1880 MHz or 1920-2170 MHz. In rural areas, 4G signals are usually found on 800 MHz, while in cities and urban areas, there are a variety of different frequency bands. Therefore, it is very likely that there is a supporting 4G or 3G band for your device,

The device should be placed in a cool and dry place to avoid temperature and high temperatures.

Installing it is as easy as installing an old TV. The cables have plugs and will become a ladder and a drill to mount the outdoor antenna to a wall or a wall on a roof. It may take some testing to find the spot with the best signal performance.
